Robbins Geller Rudman & Dowd LLP has filed a securities class action lawsuit against Richtech Robotics Inc. (NASDAQ: RR) on behalf of investors who purchased the company's publicly traded securities between January 27, 2026 and January 29, 2026. The lawsuit alleges that Richtech Robotics made false claims about having a collaborative and commercial relationship with Microsoft, which was later denied by Microsoft.

Why it matters

This lawsuit highlights the importance of public companies accurately representing their business relationships and partnerships. Investors rely on truthful disclosures when making investment decisions, and false claims can lead to significant stock price volatility and losses.

The details

The class action lawsuit alleges that Richtech Robotics claimed it had a collaborative and commercial relationship with Microsoft, when in fact Microsoft denied any such partnership. On January 29, 2026, Hunterbrook Media published an article stating that "Richtech participated in an AI Co-Innovation Lab engagement, which is a standard customer engagement focused on exploring and prototyping AI solutions using Microsoft technologies . . . . There is no commercial element in this lab engagement." This news caused Richtech Robotics' stock price to drop more than 29% over two trading days.

  • The class period is from January 27, 2026 to January 29, 2026 at 12:00 p.m. EST.
  • The lead plaintiff deadline is Friday, April 3, 2026.
